System returned to ROM by power-on

One of our 7206 have problems with self-boot. Some says that the message system returned to ROM by power-on means that someone have physically booted the router or the we've had loss of power. Is this true or can there be other explanations for the outline in sh version? The sh log shows this msg: No More free buffer in vnm_dsprm_free_msg_Q

00:00:20: vnm_dsprm_line_status_from_port: failed on 5 card

Re: System returned to ROM by power-on

If you have the message "returned to ROM by power-on" means physical AC power was interrupted by whatever means. If someone boots the router (software reset i.e. CLI), the message will be ".... system restarted by reload."
